The 33 ft stone tower was once a hunting lodge and a windmill before its 21st century transformation.

It is now on the market with estate agents Strutt & Parker for a guide price of £1.75m.

The property has a large open-plan kitchen, dining and sitting rooms and two bedrooms with en-suite bathrooms built underground.

The tower, which is about 24ft wide at the base and 2.5ft thick walls, has a media room below ground level, a reception hall and two bedrooms, one of which is en-suite.

The Grade II listed tower was part of the Bathhurst Estate dating back to the 1700s and served as a hunting lodge to Cirencester Park, a nearby stately home. The castellation was added at a later date.

The home is surrounded by four acres of gardens and grounds and has an outdoor heated swimming pool sunk into the landscape

“Although a period building will always need upkeep and repairs, and follies in particular will have an unconventional layout, any such constraints are often outweighed by the charms of the architectural style.”
